Really steemit here and digging into it with Google searches or other searches is the closest you'll find to that. You could also perhaps find some answers from people on the SteemSpeak discord server as some people from Steemit Inc. do hang out there as well as other developers.

It's a lot to keep up with. If I were developing for it I'd be paying more attention. My knowledge just comes from being very involved here for about a year. I do jump into SteemSpeak sometimes but, for me that can be very distracting and before I know it I can lose a day.
